METHOD AND APPARATUS FOR INSERTION OF A SENSOR
First Claim
1. An insertion device, comprising:
- a guidance structure having an exit port and providing axial support to a flexible analyte sensor, the guidance structure adapted to allow passage of the flexible analyte sensor upon application of a motive force to the analyte sensor; and
an injection activation device associated with the guidance structure, the injection activation device having a mechanism adapted to apply a high speed motive force to the flexible analyte sensor such that, when the high speed motive force is applied, the flexible analyte sensor moves at least partially through the guidance structure and at least partially passes through the exit port to cause insertion of only the flexible analyte sensor into skin.

Abstract
A device and method for delivering a device such as a sensor or fluid transport structure or a fluid transport structure sensor combination into, for example, mammalian skin. Such a device allows a sensor to penetrate mammalian skin without the use of an introducer device such as a needle. A device in accordance with embodiments of the present disclosure includes a housing for attachment to mammalian skin including an exit port for receiving the distal end of a biosensor and an injection activation device including a mechanism for forcing the sensing device from a first position within the housing, through the exit port to a second position, with sufficiently high velocity to partially penetrate the mammalian skin.
